The EASA Annual Safety Review (ASR) for 2016 covers a review of aviation safety in Europe for 2015. In the section Commercial Air Transport Aeroplanes there was one fatal accident in Europe in 2015, which was the Germanwings accident on 24 March 2015. There was a higher number of non‑fatal accidents involving EASA Member States operators in 2015 than the 10-year average. At the same time, there was a 24% reduction in the number of Serious Incidents against the 10 year average.
In Non-Commercial Aeroplanes there was a reduction in the number of fatal accidents compared with the 10-year average and also a reduction in the number of fatalities. In Aerial Work/Part SPO Aeroplanes there were two major accidents in 2015. One was an airborne collision between two LET-410 aircraft taking part in Parachuting operations in Slovakia that resulted in 7 fatalities. The other occurred at the Shoreham Air Show in the United Kingdom and resulted in 11 ground fatalities.
Two versions of the ASR are available here, the full document covering all areas of aviation and the summary document focussing on the key highlights.
